Description

  The present invention relates to a seat fixing tool for fixing a vehicle seat such as a rear seat to a vehicle body in a vehicle such as a passenger car, and a vehicle seat provided with the seat fixing tool.

Conventionally, as a fixing configuration for fixing a vehicle seat to a vehicle body panel, for example, configurations disclosed in Patent Literature 1 and Patent Literature 2 have been proposed. In these conventional configurations, a metal frame-like wire is embedded under the cushion pad of the seat. A pair of substantially U-shaped locking portions project from the lower surface of the cushion pad at the front portion of the frame wire. On the floor panel of the vehicle body on which the seat is placed, a pair of cylindrical resin-made receiving members are disposed. When the seat is installed on the vehicle body frame, the locking portion is elastically fitted into the receiving member, and the seat is detachably fixed to the floor frame.
Japanese Utility Model Publication No. 62-17916 JP 2001-37575 A

However, these conventional configurations have the following problems.
(1) The frame-like wire needs to have high rigidity so that the fitting state of the locking portion with respect to the receiving member can be firmly maintained. Therefore, the frame-like wire is made of steel and has a large wire diameter, which makes the entire sheet heavy.

(2) Since it is necessary to provide a receiving member made of synthetic resin on the vehicle body frame side in addition to the frame-shaped wire, the number of parts increases and the configuration becomes complicated.
(3) Since the frame-shaped wire is a steel material, it is in an adhesive state with urethane of the cushion pad. Therefore, when the cushion pad of the seat is discarded, it is difficult to peel the urethane foam of the cushion pad from the frame wire. For this reason, it takes time and effort to dispose of the waste together with the separation process.

  The present invention has been made paying attention to such problems existing in the prior art. The main object of the present invention is to provide a seat fixture that can simplify the configuration of fixing the seat to the vehicle body panel.

A claw portion that is detachably hooked to the hook portion of the vehicle body panel is provided at the tip portion of the pillar portion that protrudes to the outside from the bottom surface of the cushion pad.

  Therefore, by using this seat fixture, unlike the conventional configuration, there is no need to provide a receiving member made of synthetic resin on the vehicle body panel side, and the number of parts can be reduced and the configuration can be simplified. Moreover, in the vehicle seat equipped with this seat fixture, the weight can be reduced as compared with the conventional configuration in which a metal frame wire is embedded in the cushion pad. Furthermore, in the vehicle seat equipped with this seat fixture, when the cushion pad is disposed of, if the seat fixture is a synthetic resin other than urethane, the seat fixture can be easily removed from the urethane foam of the cushion pad. Therefore, it is possible to easily dispose the cushion pad with separation.

Next, the configuration of the seat fixture 24 and the configuration of the parts related thereto will be described in detail.
As shown in FIGS. 5 to 8, the seat fixture 24 is provided with a square cylindrical pillar portion 31 that is open at both ends and embedded in the cushion pad 22 at the base end portion. A plate-like anchor portion 32 extending in a direction orthogonal to the extending direction of the pillar portion 31 is integrally formed on the base end edge of the pillar portion 31. A plurality of through holes 33 are formed in the anchor portion 32. When the base end portion of the pillar portion 31 of the seat fixture 24 is embedded in the bottom portion of the cushion pad 22, the anchor portion 32 is substantially horizontal in the urethane foam of the cushion pad 22 as shown in FIG. 3. The urethane foam is inserted into each through-hole 33 while being embedded so as to be positioned in a plane. Therefore, in the embedded state of the anchor portion 32, the anchor effect by the anchor portion 32 is exhibited, and the pillar portion 31 of the seat fixture 24 is firmly fixed to the cushion pad 22 so as not to come off.

  As shown in FIGS. 3 to 8, a movable piece 35 is cut out by forming a substantially inverted U-shaped slit 34 on the front wall of the tip of the pillar portion 31. A claw portion 36 protrudes from the outer surface of the movable piece 35, and a guide slope 36a is formed at the lower portion thereof. As shown in FIG. 8, above the claw portion 36, the movable piece 35 of the pillar portion 31 is removed so as to correspond to the claw portion 36 with a predetermined interval L in the extension direction of the pillar portion 31. A flange portion 37 that is parallel to the anchor portion 32 is integrally formed on the outer peripheral surface of the portion. The predetermined interval L corresponds to the thickness of the floor panel 27. The flange portion 37 has a smaller area than the anchor portion 32. Further, a plurality of reinforcing ribs 38 are integrally formed between the lower surface of the flange portion 37 and the outer peripheral surface on the front end side of the pillar portion 31. Then, as shown in FIG. 3, the vehicle seat 21 is placed on the floor panel 27, and the leading end portion of the pillar portion 31 in each seat fixture 24 is fitted in the fixing hole 28 of the floor panel 27. At this time, the guide slope 36 a engages with the inner edge of the fixing hole 28. For this reason, the movable piece 35 is deformed against its own elasticity by the action of the guide slope 36a, and the passage through the fixing hole 28 of the seat fixing tool 24 is allowed. Next, the flange portion 37 is brought into contact with the upper surface of the floor panel 27 at the periphery of the opening of the fixing hole 28, and the claw portion 36 is detachably hooked on the lower surface of the floor panel 27 by the elasticity of the movable piece 35. . Therefore, in this state, the floor panel 27 is sandwiched between the claw portion 36 and the flange portion 37.

  A guide surface 38 a is formed at the outer edge of each reinforcing rib 38 so as to be inclined toward the lower end of the pillar portion 31. The insertion of the pillar portion 31 into the fixing hole 28 of the floor panel 27 is guided by the action of the guide surface 38a.

  As shown in FIGS. 3 to 8, a lid plate portion 39 that is parallel to the anchor portion 32 is formed integrally with the pillar portion 31 between the anchor portion 32 and the claw portion 36. The lid plate portion 39 is smaller than the anchor portion 32 and has a larger area than the flange portion 37. Three substantially semicircular positioning recesses 40 are formed on the outer peripheral edge of the cover plate portion 39. The positioning recess 40 is formed at two positions on the left and right of the front edge of the lid plate portion 39 and at one position in the center of the rear edge. The concave portion 40 is disposed asymmetrically on the opposite side of the lid plate portion 39. A closing plate portion 39a is formed on the inner peripheral surface of the pillar portion 31 so as to correspond to the cover plate portion 39, and the inside of the pillar portion 31 is partitioned and closed between the openings at both ends by the closing plate portion 39a. . When the seat fixture 24 is embedded in the cushion pad 22, as shown in FIGS. 9 to 12, when the seat fixture 24 is set on a molding surface 41a of a molding die 41 described later, this cover plate is used. The positioning recess 40 on the portion 39 is engaged with the three positioning pins 43 on the molding surface 41a. In this state, the opening of the recess 42 of the molding die 41 is closed by the lid plate portion 39 and the closing plate portion 39a, and the inside of the pillar portion 31 is inside the recess 42, that is, the tip portion side of the pillar portion 31. The outflow of urethane foam to the water is suppressed.

Next, the structure and molding method of a mold for embedding and molding the seat fixture 24 in the cushion pad 22 will be described.
As shown in FIG. 9, in the molding surface 41 a of the molding die 41, a recess 42 for setting the seat fixture 24 is formed at a location where the recess 22 a of the cushion pad 22 is molded. Three positioning pins 43 that can be engaged with the positioning recesses 40 on the lid plate portion 39 of the sheet fixture 24 are formed in a protruding manner on the molding surface 41 a of the molding die 41 at the opening periphery of the recess 42. .

  Then, when the sheet fixture 24 is set in the recess 42 of the molding die 41, the tip end portion of the pillar portion 31 of the sheet fixture 24 is inserted into the recess 42 as shown in FIG. 10. Thereafter, when the positioning recesses 40 on the sheet fixture 24 side are engaged with the positioning pins 43 on the molding surface 41a side, as shown in FIG. It is latched and held at a predetermined set position protruding inward. In this state, the opening end portion of the recess 42 of the molding die 41 is closed by the lid plate portion 39 of the sheet fixture 24.

  In this case, the three positioning recesses 40 and the corresponding positioning pins 43 are arranged at two places on the front side and one place on the rear side, and are asymmetrically arranged in the front and rear. For this reason, it is possible to prevent the seat fixture 24 from being positioned in a predetermined direction in the recess 42 of the molding die 41 and to set the seat fixture 24 in the wrong mounting direction with respect to the recess 42. it can. Further, since the sheet fixing tool 24 is locked to the molding surface 41a of the molding die 41 by three-point support by the engagement of the three positioning pins 43 and the positioning recess 40, the sheet fixing tool 24 is fixed to the predetermined position. Can be held in a stable state at the set position.

  Then, in this state, after closing the molding surface 41a of the molding die 41, as shown by a chain line in FIG. 11, by foaming urethane foam in the molding die 41 and molding the cushion pad 22, In the portion of the recess 22 a of the cushion pad 22, the base end portion of the pillar portion 31 of the seat fixture 24 is embedded in the cushion pad 22. In this case, the opening end portion of the recess 42 on the molding die 41 side is closed by the lid plate portion 39 of the sheet fixture 24, and the inside of the pillar portion 31 is closed by the closing plate portion 39a. There is no possibility that the urethane foam will flow out to the tip end side of the pillar portion 31 of the sheet fixture 24. Therefore, as shown in FIG. 12, the seat fixture 24 can be embedded and molded with respect to the cushion pad 22 in a state where the tip end portion of the pillar portion 31 protrudes outward from the bottom portion of the cushion pad 22. In this state, one side surface of the cover plate portion 39 forms a part of the inner bottom surface of the recess 22 a of the cushion pad 22.

  At the time of molding, as shown in FIG. 12, the anchor portion 32 of the seat fixture 24 is embedded in the urethane foam of the cushion pad 22, and the urethane foam enters the respective through holes 33. Molded. For this reason, the pillar portion 31 of the seat fixture 24 can be firmly secured to the cushion pad 22 and prevented from coming off.

  Thereafter, as shown in FIG. 12, when the molding surface 41a of the molding die 41 is opened and the cushion pad 22 is removed from the molding surface 41a, the positioning recesses 40 on the seat fixture 24 side become the molding surface 41a side. The positioning pins 43 are separated from each other. In this case, since each positioning recess 40 is formed in a semicircular shape, for example, even when the molding die 41 is demolded and rotated around the lower position in FIG. Escape from inside to escape. Therefore, each positioning recess 40 can be easily detached from each positioning pin 43.

  Incidentally, in the case where a plurality of positioning holes are formed on the sheet fixture 24 side instead of the recesses 40 and the positioning holes are engaged with the positioning pins 43 on the molding surface 41a side, the positioning is performed. Due to the interference between the holes and the positioning pins 43, it is difficult to detach the positioning holes from the positioning pins 43 when the molding die 41 is turned off. Then, there is a possibility that the sheet fixture 24 made of synthetic resin may be damaged by the twisting with the positioning pins 43 at the time of detachment. In order to prevent this, it is necessary to make the positioning hole larger than the diameter of the positioning pin 43, but if this is done, the positional accuracy of the sheet fixture 24 cannot be ensured.

  The skin 23 is set in the molding die 41 and the cushion pad 22 is molded in the skin 23 so that the skin 23 is attached to the outer surface of the cushion pad 22 or the cushion pad 22. You may make it cover the cushion pad 22 after shaping | molding.

  In this way, when the sheet fixing tool 24 is inserted into the fixing hole 28 of the floor panel 27, the flange 21 is brought into contact with the upper surface of the floor panel 27 and the claw portion of the movable piece 35 is formed in the sheet 21 thus manufactured. 36 engages with the lower surface of the floor panel 27, and the floor panel 27 is sandwiched between the flange portion 37 and the claw portion 36. Therefore, in this state, the seat 21 is set at a predetermined position in the passenger compartment.

  Further, if the seat fixture 24 is provided on the cushion pad 22 so that the movable piece 35 on which the claw portion 36 is formed is on the front side of the vehicle, the work of removing the seat becomes easy. For example, when removing the sheet 21 from the floor panel 27 for cleaning the sheet 21, a tool such as a screwdriver is inserted between the sheet 21 and the floor panel 27 and the movable piece 35 is pushed against the elasticity. If it bends, the nail | claw part 36 will remove | deviate from the lower surface of the floor panel 27. FIG. Therefore, the sheet 21 can be removed from the floor panel 27 by pulling out the sheet fixture 24 from the fixing hole 28 in this state.
